Product details
This fifteen-sixteenths-inch Compact Tandem master packages both reservoir chambers above a chrome powder-coated cylinder body. The threaded pushrod is included, so the installed length and pedal attachment must be checked along with the compact housing dimensions. Bill Wood's founding of Wilwood Engineering in 1977 established a disc brake design and manufacturing business based in Camarillo, California. Calipers, rotors, master cylinders, fittings, valves and brake lines form its range for motorsport, street-performance and specialized applications. Choosing a service component still requires checking the mating parts and overall system configuration.

Fitment & Compatibility
Use a secure mounting flange with 3.22–3.40-inch centers and verify full piston return at rest. Both circuits require their own correctly routed lines, and the master must complete its 1.10-inch stroke before the pedal stops. Wilwood specifies factory rebuilding for this tandem design rather than routine user disassembly.
